Independent shopping perspective
The Korena take
Reactor 50 is a 50W 1x12 modeling combo centered on Positive Grid’s BIAS X engine and Agentic DSP. Its Reactor app can build and refine tones from text prompts, audio references, and conversational adjustments, while the amp provides six selectable voicings, onboard effects, and physical gain, EQ, master, and volume controls. Select 1W, 25W, or 50W to match the session, then use USB-C audio, MIDI In, the effects loop, line out, Bluetooth, or headphones as the rig requires.
Strong match
Who this is for
- Moving between low-output home practice, studio tracking, and rehearsal with selectable 1W, 25W, and 50W settings.
- Players who want to create or revise guitar tones in the Reactor app from prompts or audio references.
- Studio or performance rigs that need USB-C audio, MIDI In, effects loop, line out, or headphones.
Consider the trade-offs
When to look elsewhere
- Players who need the Reactor Control footswitch included; footswitch support is listed separately from the amplifier.
